Here are 4 steps to defog your windshield twice as fast in the morning and the science behind why it works. Thanks for watching from the bottom of my nerdy heart.

These are all great ideas but I heard running an air conditioning condenser in 61 F or below can cause it to freeze. Or is this only home ac units?

Living in northern michigan ive noticed it helps a lot in terms of ice build up when its snowing if you turn off the heat and crack windows before you get home, letting internal temperatures cool. Of course remote start is the ultimate solution, love it!

What about when the condensation is outside,so you turn on the wipers,but it keeps fogging on the outside, even when driving. How to solve that?

Dude, loved when i found you ab a year ago. Obv. youre fresh, ALnets stats Im sure back that up. Been able to finally watch ALnets vids w my momma and enjoy thx to you. When its that time to open the app and browse such videos, when i come to your channel and start to go back on vids I have not seen. When you make a simple analogy to explain basic cause n affect ie; the gatorade w towels for humidity yadda yadda.. its so great. Thats all i wanted to say. It is so fresh to be able to paint a picture of a complex reaction (for some) and have everyone see it so vividly. Youre fresh. Loved this

Why is no one talking of the input parameters of the equation: When you park your car at night, it would make a huge difference to open the windows beforehand to let the warm humid air escape and thereby removing as much humidity as possible, no? The fresh cold air will hold much less water and therefor lead to much less condensation to begin with.

To keep snow from sticking to my car. I chill it way down. So nothing melts on. Then it just brushes off.
Samuel Mellert

@Suki Rice Hahaha.. I'm not suggesting to leave them open.. just, to give the car like two minutes to release the warm humid air, before parking it and leaving it for the night.

For one. In most cars. The ac compressor automatically comes on when you turn on the defogger to help dry the air. For 2. In most all cars. You literally can't have the recirculate function on when you have the defogger on anyways... This is because the exit for the defogger/defroster is the entrance for recirculating the air. You should probably try to understand how vehicles work before trying to tell people how to operate them... Also. There's a difference between fog and frost. Fog is on the inside. Frost is on the outside. Usually. Unless you have a ridiculously high amount of moisture inside your vehicle in winter. This means defrosting both takes longer and is a bit of a different process than defogging.

More effective option: Step 1) Buy remote start system Step 2) Install or pay someone to install remote start system Step 3) Remote start car Step 4) Get in your warm car and immediately drive away while laughing at your neighbors while they scrape snow & ice from their cars

....Hmmm, but why does heating the air inside the car help reduce the condensation on the windshield? I thought the condensation on the windshield was on the outside of the windshield, not inside on the inside of the car. So heating up the air inside the car would then heat up the windshield, giving the water molecules in the condensation droplets more energy to vaporize? Maybe?

Do u just wipe shaving foam.over the window? Seriously, thats the only new science (rest is obvious), but no explanation!! Would any shaving foam do? How to apply, how long does it last...such a missed opportunity for some real science on how/why shaving foam works.

This is really helpful. How about exchanging the inside air just before parking for the day/night? My thinking is that it will take humid air out and bring dry air in. Makes sense?

Can't use the a/c with the heat on and vice versa, but the shaving cream thing was cool. Now I'm wondering is air can be so hot on any planet that water can boil... Like boiling fog.

Worst I've had so far, I was a couple hundred miles away from home coming home at night and the road I was on was closed so I literally had to take back roads in the mountains, losing signal most of the time, and it was super super foggy. And there was deer and other wildlife everywhere making it that much worse. I could not figure out how to get the windows cleared (it was like 2 months after I started driving) I basically ended up driving with my windows down bc it cleared it up a little and I kept clearing the inside of my windshield with my hands 😂

Another one that works the best is silica gel packs like the ones found in new shoes and purses. Just a couple left on the dash over night prevents almost all of the fog off the window plus recycling is never a bad thing my daughter and I both love this channel. Keep that energy Mark.

Strictly speaking air does not ‘hold’ water. The air and water is a mechanical mixture not a solvent-solute system in the way, for example, that water and table salt is. Increasing the temperature of air does not increase its holding capacity (i.e. solubility) for water vapour in the same way that the solubility of liquid water for table salt increases with temperature. The higher air temperature means that the partial pressure of water vapour in the air-water mixture is greater than it is at a lower temperature thus the quantity of water in a given volume of the mixture is more in the hotter mixture. Water content in air can be wholly explained by the physical properties (p-V-T) of water alone. It has nothing to do with air

In electric and plug in hybrid cars, just set the car to precondition/warm up the cabin 20 minutes before you normally leave for work. This same setting will also defrost the car when the condensation freezes...

Marc: you forgot two elements, clean dust free windshield both inside and outside. Dust promotes condensation (e.g. clouds require dust particles to form) and also there is inside, and outside condensation, which require different techniques. If condensation is outside the windshield, heat the windshield up. If inside, chill it down with the a/c.
